+================================
+
+Ensure that every value that in a ``throw`` expression is an instance of
+``std::exception``.
+
+Exception types should inherit from ``std::exception`` so they can be
+handled consistently and caught as ``std::exception``.

This is too generic, can we:

Deriving all exceptions from ``std::exception`` ensures callers can catch every possible exception through a single catch block and always have access to ``what()`` method for diagnostics. Throwing arbitrary types creates hidden contracts, breaks interoperability with the standard library, and risks triggering a program termination.
